Product Description:
The UNID UW series solenoid valve is designed with a pilot diaphragm-driven mechanism and operates as a normally closed valve. This means it remains closed when de-energized and opens upon receiving electrical power. Such a design ensures reliable operation in various control systems.
One of the key advantages of this series is its ability to function directly under zero pressure differential, which broadens its range of applications. Depending on the valve size, the body is constructed from different materials: forged brass is used for sizes ranging from 3/8" to 1", while cast bronze is employed for larger sizes from 1¼" to 2". Both materials provide excellent resistance to corrosion, enhancing durability.
The standard sealing material for these valves is NBR, suitable for fluids up to 80°C. For applications requiring higher temperature tolerance, seals made of Viton or Silicon are available, capable of withstanding temperatures up to 130°C. To accommodate various international piping systems, the valves come with standard threaded connections such as BSPT, NPT, and BSP.
The coil voltages commonly offered include 110VAC, 220VAC, and 24VDC, while special voltage options can be provided upon request to meet specific customer needs. Due to its versatile features, the UW series solenoid valve finds wide usage in fields like water treatment, industrial automation, HVAC systems, and light oil transfer processes.
Features:
The pilot diaphragm structure is engineered to provide sensitive opening and closing actions, ensuring excellent anti-clogging performance. This design enhances the reliability and responsiveness of the valve in various operational conditions.
Featuring zero pressure differential operation, the valve does not require any minimum pressure to function. This characteristic allows it to operate efficiently even under low-pressure scenarios.
There are dual body material options available to suit different applications. For sizes ranging from 3/8" to 1", forged brass is used, while cast bronze is chosen for larger sizes from 1¼" to 2". This flexibility ensures durability and compatibility with diverse system requirements.
The valve offers multiple seal materials to accommodate varying temperature conditions. The standard option is NBR, rated up to 80°C, while Viton or Silicon seals are available for higher temperature fluids up to 130°C.
Compatibility with multiple media types, including water, air, and light oil, makes this valve versatile. It supports a wide operating pressure differential range, detailed further in the technical data.
Various port sizes from 3/8" to 2" are provided, with flow coefficients (Cv) ranging from 2.4 to 48, allowing the valve to meet different flow requirements effectively.
The maximum operating pressure differential is up to 7 kgf/cm² for air, and up to 5 kgf/cm² for water and light oil, ensuring robust performance across applications.
Threaded connections are available in BSPT, NPT, and BSP standards, offering flexible installation options to suit different piping systems.
The coil voltage tolerance is designed for stable operation, with an allowance of AC ±10% and DC ±1%, ensuring consistent performance under voltage fluctuations.
Finally, the compact and lightweight design of the valve makes it easy to integrate into existing systems, saving space without compromising functionality.
